The New Gascony system was one of five systems to be colonized between the early twenty-seventh century and the early twenty-eighth century. The capital world of the Tortuga Dominions, Tortuga Prime, was colonized by the remains of the 237th Light Cavalry Regiment in the closing stages of the Reunification War. The 237th being an Armed Forces of the Federated Sunsregiment that took heavy damage in a wasteful military operation against Sterope, leading to the survivors deserting the Federated Suns. A generation after settling Tortuga Prime, the settlers embraced a new identity, the Pirates of Tortuga, and conducted pirate raids against the Federated Suns to seize equipment and machinery to expand their initial holdings; this worked well enough that within a century, the stable and self-sufficient colony on Tortuga was well-established enough to begin the colonization of other worlds, leading to the settlement of New Gascony and four other worlds.[3]
